ITPEC IP October 2025 Question 75
ITPEC IP October 2025 — Question 75 of 100
Wirelessly connecting game controllers to a console is a Bluetooth use case — Bluetooth provides short-range radio communication between nearby personal and household devices.
Controllers, keyboards, mice, headsets, phones, and appliances commonly use Bluetooth to exchange data without cables over a relatively short distance and with modest power consumption.
Answer (a)
Why not others:
- (b) a navigation receiver obtains positioning signals from GPS satellites
- (c) a phone camera reads the visual pattern of a QR code
- (d) an automatic gate communicates with a contactless IC card using short-range RFID or NFC technology
Key rule: Bluetooth links nearby electronic devices; GPS provides satellite positioning, QR is optical encoding, and NFC or RFID reads contactless tags and cards.
